Abstract: An image forming apparatus is connected to a paper processing apparatus and includes an image forming unit, a nip part and a hardware processor. The image forming unit performs image forming on continuous paper being conveyed on a conveyance path. The nip part nips the paper on the conveyance path. The processor selectively performs first control and second control according to an output timing of a conveyance control signal if the signal is output from the paper processing apparatus or the image forming apparatus. In the first control, the processor notifies the paper processing apparatus of permission to start or stop conveying the paper after causing the nip part to perform a press-and-contact operation or a separation operation. In the second control, the processor notifies the paper processing apparatus of the permission without causing the nip part to perform either operation.

Abstract: In an image forming apparatus 1 capable of reserving a plurality of printing jobs, the suspended state retention time for retaining the suspended state is preset by the operation of an operation section 142. When a printing job during output operation has been suspended, a timing section 17 starts to measure the preset suspended state retention time. If the printing job having been suspended is not resumed even after the lapse of the suspended state retention time and there is a subsequent printable job, the order of the printing jobs is changed and the subsequent printing job is executed.
